Feb 10th, 2011 Today we learned Logan's method for doing division. You are more than welcome to use it if you like it. The homework is on page 106 # 1, a, c, e, g, j, l, 2, ac, e, g, j, l, 4, 5, 6, 7. We will have and hour of class time to work on these tomorrow. They will be due on Monday.
I try to think of the biggest multiple of 5 that goes into 926 without going over. I know that 5 x 100 is 500 and 5 x 200 is 1 000 so I want to try a number in between these two, how about 150? 150 x 5 = 750 so I write 150 outside of the line and 750 inside the box under 926 and subtract. Now I try to think of the biggest multiple of 5 that goes into 126 without going over. I know that 5 x 50 is 250 and 5 x 30 is 150. 5 x 30 is really close to what I want so I'll just use that. 30 x 5 = 150 so I write 30 outside of the line and 150 inside the box under 176 and subtract. Now I try to think of the biggest multiple of 5 that goes into 26 without going over. I know that 5 x 5 is 25 5 x 5 = 25 so I write 5 outside of the line and 25 inside the box under 26 and subtract.
1 is my remainder because 5 cannot go into 1 it's too big so I know that I am done. I add up all the numbers on the outside 150 + 30 + 5 and then R1
Therefore our answer is: 185R1

Using estimation to divide
Steps: 1. Break down the divident into multiples of the divisor 2. Divide your broken down numbers by the divisor 3. Add 4. Check your answer using multiplication 5. Circle your answer
Eg. 4|345
1. 345 = 300 + 40+ 5 I don’t know if 300 is a multiple of 4 so I’, going to break 300 into 200 + 100 because I know both of those numbers are divisible by 4 And I know that 5 = 4 + 1 and 4 is divisible by 4 still 1. = 200 + 100 + 40 + 4 + 1 2. = 50 + 25 + 10 + 1 R1 Because 1 cannot be divided by 4 I know that is my remainder, that is what is left over 3. = 86 R1
4. Check:
286 x 4 +R1 344 +1 = 345
5. Circle my answer which I can’t do on this webpage.

Here are some videos that show you how to long division.
The first video is really good because it reminds you what a divisor and dividend is but you must STOP WATCHING AT EXACTLY 3:08 sec.
The second video is well done too. Don't be afraid because he is dividing bigger numbers that we were in class because the method, the steps that you do are the same . The only difference is that you just repeat steps 2-5 in our notes. When there are no digits to bring down anymore you know that you are done and whatever number you have left over is your REMAINDER!
Please do question 1a, b, c, d as well as question 3 on page 102 of your math textbooks.
Jan 26th, 2011 Today we discovered a neat relationship between geometry and arithmetic. If we are trying to find the factors of a number (say 12) we can make a rectangle with and area of 12 units 2. Whatever the base and height of our rectangle are we know that they are also factors of 12! If a number is a factor that means that the factor divides evenly into the bigger number.
12 for example has factors of 1, 2, 3, 4, 6, 12.
I can build a rectangle with a base of 1 and a height of 12 so it would be a tall and skinny rectangle I can also build a rectangle with a base of 2 and a height of 6 it would still be tall and skinny but not as much I can build a rectangle with a base of 3 and a height of 4 this would almost be a square I can build a rectangle with a base of 4 and a height of 3 this is the same as the one above, just sideways. Similarly a rectangle with a base of 6 height of 2 and base of 12 and height of 1.
All you have to do for homework is find as many rectangles as possible that have an area of: a) 169 units 2 b) 144 units 2 c) 225 units 2 Draw all the rectangles that you find and label the base and height. Get your parents to help you!

Say hi to Binomial Bob! You'll have to imagine that I drew the arrows on the example I can't do that on this website, sorry.
Eg1 (38) (16) 1. 38 = 30 + 8 & 16 = 10 + 6 (30 + 8) (10 + 6) = 48 + 80 + 180 + 300 2. 8 x 6 = 48 3. 8 x 10 = 80 4. 30 x 6 = 180 5. 30 x 10 = 300 6. Add up: 48 + 80 + 180 + 300 = 608 (I suggest that you add these vertically, meaning to stack them)
Remember to circle your answers!
Here are the four questions that you need to complete for homework on Monday.

Please read through these all as I am sure it will help. If you want you could do the corrections for your test and resubmit them on a separate piece of loose leaf. I will look at them and help you if you still have any questions.
Let's say that anyone who is wanting help can come into class Tuesday or Thursday before school at 8:30 and I will have extra help for anyone who wants it.
Also I am have put up some links to a website that has some fun math games to help you with your multiplication up to 12. Try them out if you want. Let me know how fast you can get them done in. PS: I have candy, this may be a way to get some on Halloween.
Dear Grade Fives, I am so sorry to tell you this but not everyone has finished the math test and for that very reason I will not be posting the answers to the test on this website until everybody has completed the test.
Please remember to work on your "Worm Story". It should be written in the first person and you must have your main point clearly identifiable, as well as a minimum of three details which support that main point. REMEMBER: this is still a rough draft. We will work on fixing up grammar and punctuation in class on Monday and Tuesday, Word choice on Wednesday and then we are reading them to our Kindergarten buddies.
Have a great weekend and enjoy the mild weather!
October 9th, 2010 Here are the answers to the Extra Practice Sheets for math. Hope that you can access them. If not please email me and I will try to fix the problem. Have a great long weekend. See you on Tuesday.

Today we learned Logan's method for doing division. You are more than welcome to use it if you like it.
The homework is on page 106 # 1, a, c, e, g, j, l, 2, ac, e, g, j, l, 4, 5, 6, 7. We will have and hour of class time to work on these tomorrow. They will be due on Monday.
Eg. of Logan's Method
5| 926|
- 750 | 150
. 176 |
- 150| 30
. .26 |
- 25 | 5
. . 1 |
185R1
I try to think of the biggest multiple of 5 that goes into 926 without going over.
I know that 5 x 100 is 500 and 5 x 200 is 1 000 so I want to try a number in between these two, how about 150?
150 x 5 = 750 so I write 150 outside of the line and 750 inside the box under 926 and subtract.
Now I try to think of the biggest multiple of 5 that goes into 126 without going over.
I know that 5 x 50 is 250 and 5 x 30 is 150. 5 x 30 is really close to what I want so I'll just use that.
30 x 5 = 150 so I write 30 outside of the line and 150 inside the box under 176 and subtract.
Now I try to think of the biggest multiple of 5 that goes into 26 without going over.
I know that 5 x 5 is 25
5 x 5 = 25 so I write 5 outside of the line and 25 inside the box under 26 and subtract.
1 is my remainder because 5 cannot go into 1 it's too big so I know that I am done.
I add up all the numbers on the outside 150 + 30 + 5 and then R1
Therefore our answer is: 185R1

Using estimation to divide
Steps:
1. Break down the divident into multiples of the divisor
2. Divide your broken down numbers by the divisor
3. Add
4. Check your answer using multiplication
5. Circle your answer
Eg. 4|345
1. 345 = 300 + 40+ 5 I don’t know if 300 is a multiple of 4 so I’, going to break 300 into 200 + 100
because I know both of those numbers are divisible by 4
And I know that 5 = 4 + 1 and 4 is divisible by 4
still 1. = 200 + 100 + 40 + 4 + 1
2. = 50 + 25 + 10 + 1 R1 Because 1 cannot be divided by 4 I know that is my remainder, that is what is left over
3. = 86 R1
4. Check:
286
